HIRAM C. HUFF, OF VVINANS, SOUTH DAKOTA.

WINDMILL.

#:PEGIFICATION forming part of Letters Patent No. 698,116, dated April 22, 1902. Application filed January 20, 1902. Serial No. 90,532. (No model.)

To all whom it may concern.-

Be it known that I, HIRAM O. HUFF, a citizen of the United States, residing at Winans, in the county of Roberts and State of South Dakota, have invented a new and useful Windmilhof which the following is a speci fication.

The invention relates to improvements in windmills.

The object of the present invention is to improve the construction of windmills and to provide a simple and comparatively inexpensive one adapted should the wind increase in force beyond a predetermined degree to form a supplemental tail or vane at right angles to the main tail or vane, whereby the wind- Wheel will be turned out of the wind, and capable when the wind abates of automatically throwing the Wind-wheel into the wind.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is an elevation of a windmill constructed in accordance with this invention and illustrating theposition of the parts when the windmill is in operation, the position of the wind-wheel being indicated by dotted lines. Fig. 2 is a similar view illustrating the position of the parts when the wind-Wheel is turned out of the Wind. Fig. 3 is a plan view of a portion of the windmill.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

l designates a rotary frame mounted upon a tower 2 in any suitable manner and provided with suitable bearings for a main shaft 3, disposed horizontally and designed to carry a wind-wheel (not shown) of any desired construction, and it also has mounted upon it a brake-wheel 4, which is engaged by a brakeshoe 5 to check and stop therotation of the wind-wheel when the latter is turned out of the wind, as hereinafter explained. The brake-shoe is secured to a brake-lever 6, fulcrumed at one'end 7 on the rotary frame at.

one side thereof and connected at its other end 8 by a rod or link 9,with an arm 10 of a bell-crank lever 11. The bell-crank lever 11 right lever 16.

is fulorumed at its angle on the rotary frame at the bottom thereof, preferably by means of a shaft or pintle 12, and it consists of an arm 13 and diverging 31111510 and 14. The

bearings of the rotary frame, and the arms 10 and 14, which diverge, extend outward in the same general direction from the rotary frame. The arm 13 extends downward and is connected by an approximately horizontal link or rod lowith the lower arm of an up- The upright lever 16 is fulcrumed between its ends at 17, and its other arm is secured to a flexible connection 18,

shaft or pintle 12 is journaled in' suitable consisting of a rope, cord, wire, or the like and arranged on guide-pulleys 19 and 20 and extending to the base of the tower to enable the windmill to be controlled from that point.

The arm 14 of the bell-crank lever is connected by a link 21"with a curved arm 22 of a rock-shaft 23, which carries a gear 24, and the latter meshes with a corresponding gear 25 of a shaft 26. The shafts 23 and 26 are journaled in upper and lower bearings of brackets 27, and they also carry supplemental vanes 28 and'29, arranged in an upright p'osi tion and extending beyond the periphery of the hinged wheel, as indicated in Fig. 1 of the drawings-when the windmill is in operation. throughout a portion of their peripheries with The gears 24 and 25 are provided teeth, and the remainingportion of their peripheries is smooth, a suiiicient number of teeth being provided to permit the swing of the supplemental vanes and to cause the latter to oscillate in unison.

The supplemental vanes consist of stems and a curved series of blades arranged to cause the wind to tend to swing the supplemental. vanes to the right from the position illustrated in Fig. 1 to that illustrated in Fig. 2. When the blades are swung downward to the position illustrated in Fig. 2 of the drawings, they are arranged in a plane parallel tothat of the wind-wheel, and they form a supplemental vane for turning the wind-wheel out of the wind.

The main vane 30 consists of a blade mounted on a shaft 31, adapted to be rotated by the means hereinafter described "to-turn the vane from the verticalipo'sition (illustrated in Fig. 1 of the drawings) to the horizontal posit-ion, (shown in Fig.2,) whereby the main vane will be rendered ineffective and will permit the supplemental vane to control the wind wheel.

The shaft 31, which is disposed horizontally, is provided with a short arm 32, which is connected by a link or rod 33, and the latter extends from the said short arm 32 to the stem of the supplemental vane 28, being preferably secured to the same by an eyebolt 34; but any other suitable means may be employed for connecting the vane shaft or spindle with the supplemental vanes or the gears. \Vhen the supplemental vanes are swung from the position shown in Fig. 2t0 that illustrated in Fig. 1, the main vane will be returned to a vertical plane and will turn the wind-wheel into the wind.

The vane shaft is also provided with a weighted arm 3%, having an adjustable weight 35, adapted to counterbalance the weight of the supplemental vanes, and it is also capable of returning the same to the position shown in Fig. 1 when the wind abates. The weight holds the supplemental vanes in the position shown in Fig. 1, and it may be moved inward and outward on the arm to secure the desired leverage. XVhen the supplemental vanes are swung to the approximately horizontal position, (shown in Fig. 2,) the brake-shoe will be swung downward into engagement with the brake-wheeland will check the rotation of the wind-wheel and finally stop the same.

\Vhat I claim is 1. In awindmi1l,the combination of a rotary frame,a main vane carried by the rotary frame and capable of partial rotation to turn it from a vertical to a horizontalposition, apair of supplemental vanes arranged normally in an upright position and adapted to swing therefrom to approximatelya horizontal position to form a vane at an angle to the main vane for turning the wind-wheel out of the wind, gears meshing with each other and connected with the supplemental vanes, and connections between the supplemental vanes and the main vane, substantially as and for the purpose described.

2. In a wind mill,the combination of a rotary frame, a wind-wheel shaft provided with a brake-wheel, a main vane havinga horizontal seams shaft mounted on the frame and provided with a short arm, a supplemental vane arranged normally in an upright position and adapted to swing to an approximately horizontal position at an angle to the main vane, and connected with the said arm, whereby the main vane will be partially rotated when the supplemental vane is oscillated, a brakelever having a shoe arranged to engage the brake-wheel, and means for oscillating the brake-lever simultaneously with the supplemental vane, substantially as described.

In a windmill,the combination of a rotary frame, a wind-wheel shaft having a brakewheel, a main vane journaled on the frame and capable of partial rotation, supplemental vanes, gears connected with the supplemental vanes and meshing with each other to cause the said supplemental vanes to oscillate in unison, means for connecting the supplemental vanes with the main vane, an arm connected with the supplemental vanes, a bellcrank lever having divergingarms, one of the arms being connected with the said arm, a brake-lever connected with the other divergent arm, and an operating-lever connected with the beltcrank lever, substantially as described.

4. In a windmilhthe combination ofa rotary frame, a main vane movably mounted on the frame to arrange it in an effective position and to carry it to an ineffective position, supplemental vanes mounted on the frame and normally extending upward and downward therefrom and capable of swinging simultaneously in opposite directions and adapted to be arranged approximately in a horizontal position to form a vane at an angle to the main vane, and means for connecting the main vane with the supplemental vanes, whereby the main vane will be arranged in an ineffective position when the supplemental vanes are in substantially a horizontal position, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
